When it is desired to external appearance and size of the cartridge fire a small cartridge from the rifle, the carordinar'ily utilized in the rifle in which it is tridge is first placed in the casing 1 and the used. The casing is adapted to receive a breech block is then inserted behind it so that small pistol cartridge and the head of said the firing pin will contact with the cap.

A tubular breech therein is then inserted in the rifle and when block is fitted in the casing in rear of the carthe same is operated, the firing pin of the tridge and has a firing pin mounted within it rifle will be brought into contact with the pin adapted to be projected by the firing pin of 6 and this in turn will explode the cap of the the rifle so as to explode the cap of the small l cartridge and project the ball.

Fig. 2 is a section through the the operation of the device to be interfered with or the same becoming clogged. The entire attachment is formed of but three parts and cannot therefore get out of order.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. An attachment for rifles comprising an imperforate, non contractible casing, the outer surface of which simulates the shell of a cartridge ordinarily used within the rifle, said casing having an interior shoulder and thickcasing of the attachment. Fig. 3 is a similar view of the breech block, and, Fig. 4 is a detail view of a firing pin adapted to be used for exploding rim fire cartridges in a center fire rifle.

Referring to the figures by numerals of reference, 1 is a casing, the external diameter and appearance of which is that of a shell of a cartridge such as is adapted to be used in the rifle in which this attachment is adapted to be placed.

The casing has a shoulder 2 is adapt- ICC ened from said shoulder to the adjoining end of the casing, said end being rigidand unslitted said thickened portion constituting a reinforce, and adapted to surround a miniature cartridge, a rigid, non-yielding tubular, cylindrical breech block of uniform diameter adapted to be loosely seated Within the casing and to hold the head of said miniature cartridge against the shoulder, said block and the cartridge adapted to completely fill the casing, and a firing pin slidably mounted Withinthe breech block.

2. An attachment for rifles comprising a hollow casing With one end rigid and unyield ing and thickened internally and forming an internal shoulder for contact of the head of a cartridge, a tubular breech block removably PETER M. MAYVILLE.
